Current Caveats

This section lists possibly unexpected device behavior as a result of RPS use.

Note   In the following sections, the acronym RMA represents a Return Merchandise Authorization.

Catalyst 1900 Series Switch and EtherSwitch 1220

Some Catalyst 1900 Series switches and all Etherswitch 1220 switches do not operate when connected to an RPS. To recover from this problem, connect the RPS to the switch using a Cisco Systems cable with the part number CAB-RPS-2218A=.

HP 10Base-T Hub-16M

Due to a status sensor error, the serial port on HP 10Base-T Hub-16M hubs might not function when the hub is connected to an RPS. To recover from this problem, contact Cisco Customer Service for an RMA number and to exchange the RPS.

This problem has been fixed for RPS hardware revisions 9U and above. The hardware revision level is printed on a label on the bottom of the RPS.

Catalyst 2820 Series Switch

To prevent a Catalyst 2820 switch from resetting, when the Catalyst 2820 contains an eight-port repeater module and is powered by an RPS, do not use hot-swapping to install a second eight-port repeater module into the switch.

FastHub 316T and FastHub 316C Repeaters

The FastHub RPS LED might not be lit and the network management software might indicate that an RPS is not connected when a FastHub is powered by an RPS and is otherwise operating correctly. To recover from this problem, contact Cisco Customer Service for an RMA number and to exchange the FastHub.
